Application August 2, 1937, Serial No. 156,970

2 Claims.

The invention relates to windows for vehicle bodies known as ventilating windows, and particularly to windows having pivotal mountings permitting the glass panels to swing in or out for ventilating purposes.

With the present type of ventilating windows in this class, it is the general rule to employ divided rubber sea-ling members, part of which lie outside of the plane of the window panel, and

part inside. This division creates joints in the sealing members whichare diflicult to close suffioiently to make a weather-proof window. Also the portion which lies outside of the window panel is subjected to the sun's rays and weather conditions which cause deterioration and shorten the life of such sealing members. One of the objects of the present invention is to overcome these objectionable features.

Another object is to provide a window panel having its exterior surface substantially flush with the framework surrounding said window panel.

Still another object is to provide a ventilating window which requires little effort to operate.

The accomplishment of these objects as well as other improvements are attained through the employment of a one piece sealing member lying in the same plane as the window panel; this also permits the use of sponge rubber or other more resilient material than could be used with the conventional type of construction, thus affording a more easily manipulated mechanism.

The advantages of the present invention become apparent after a brief study of the following description in conjunction with the drawing which forms a part of this application, and in which:

Fig. 1 is a fragmentary elevational view of a vehicle body panel showing a ventilating window.

Fig. 2 is an elevational view of the ventilating window together with the operating mechanism.

Fig. 3 is an enlarged cross-sectional view taken substantially on lines 3-4, of Fig. 1.

Fig. 4 is an enlarged cross-sectional view taken substantially on line 4-4 of Fig. 1.

Fig. 5 is an elevational view of the window control mechanism.

As shown in the drawing, the glass panel I is mounted in a metal sash 2; metal sash 2 having pivots 3 secured thereto, which permit the glass panel I to swing in or out for ventilation purposes.

The body panel 4 is made of sheet metal, its edge portions around the window opening being turned inwardly as shown in Figs. 3 and 4. This turned-in portion may be enlarged or joined with another sheet metal unit to form the lining board 5 which supports the fabric upholstery material 6 and provides a flange for mounting of the seal ing member 1. A garnish moulding 8 is secured 5 to the lining board 5 by means of the screw 9, and helps to hold the sealing member I in position.

In Fig. 2, the operating mechanism is comprised of sheet metal members ill, I l and I2 which are 10 formed to the contour of the three sides of sash 2. Coil springs l3 are connected to the members III, II and i 2 in such a manner as to enclose the corner portions of sash 2. The assembly of the members III, II and I2 together with the coil 15 springs l3 form a tubular unit completely encircling sash 2 and through which wire l4 passes. One end of the piano wire H (or fine wire cable), is secured to member l0 at the point designated as IS. The wire I4 extends through the members II and I2 as indicated by broken lines I 4, also through coil springs l3 which are positioned intermediately between members It), I i and i2 and continues through to the opposite end of member ID and down to the pulley IS. The pulley I8 25 together with the worm "gear I! is secured to the shaft l8; the worm I9 is controlled by manipulation of the hand crank 20, Fig. 5. The lever 2| has a fixed point 22, and is attached to member ill at point 23, point 23 being free to move up 30 or down along are 2-2.

As shown in Fig. l, the ventilating window com prising glass panel I and sash 2 is provided with suflicient clearance 24 to allow said window to swing in or out about the axis of pivots 3. Whenever the occupant of the vehicle desires to completely seal the window by closing in the space 24, he should turn the crank 20 in a clock-wise direction; this would cause the pulley IE to be driven by the worm I 9 and gear l'l, exerting a 4,0 pulling force 25 on wire I4. This force 25 would tend to compress coil springs l3 and exert a pulllng force 26 on member ID, causing it to move upward due to the limitations imposed thereon by the lever 2|; this would close the space 24 45 between member I 0 and sash 2. The compression of coil springs l3 caused by force 25 would shorten the radii of their respective arcs and close in the space 24 at the corner portions. The members II and I2 would also be drawn in by this same force 25, thereby completely closing in the gap 24 around the window panel. The sealing member I is composed of sponge rubber or similar substance and insulates the members I 0, H and I2 together with coil springs l3 against coming into contact with sash 2; said sealing member 1 being forced tightly against sash 2 whenever the pulling force 25 is exerted on wire H, and making the window weather-proof.

Whenever the occupant desires to swing the window open, a reverse turn of the crank 20 will release the force 25 on wire I, and the tension of the rubber sealing member 1 will automatically force the various members back into their respective positions as indicated in Fig. 2, which provides the necessary clearance 24 to permit the window to swing freely about the axis of pivots 3.

Having thus described my invention, what I wish to secure by Letters Patent, is:

1. A ventilating window panel having pivots secured to the sash thereof, and mounted to the window frame with sufficient clearance to swing freely about the axis of said pivots; means for sealing the space between said sash and said window frame, comprising; a sealing member having its outer edge portion secured to said window frame and means for constricting its inner edge portion about the periphery of said sash.

2. A ventilating window panel having pivots secured to the sash thereof said pivots being mountedtothe window frame in such a manner as to permit said window panel to swing freely about the axis of said pivots; means for sealing said window panel in a closed position, comprising; a sealing member having its outer edge portion sealed within said window frame, and having normal clearance between said sash to permit free movement thereof; and means for constricting said sealing member about the periphery of said sash.
